I’m losing my mind trying to get my bedroom windows open as the weather gets warmer. House was built in the mid-50s; I’m having trouble finding info on how windows like these work, or how to fix them.
What seems to happen is the wood frame has grooves on the sides which slide up metal channels. The troublesome windows don’t slide up the channel, but rather push the whole assembly upwards and jam on the upper frame.
All the sites I find in google results give advice for windows painted shut, but that’s obviously not the case here.
Here’s a picture, maybe y’all recognize the style or how to get a window like this to window again:
